Researchers from Virginia Tech concluded, after analyzing satellite images, that water is submerging major cities on the east coast of the United States.
PNAS Nexus magazine indicates that comparing images taken in 2020 with images dating back to 2007 showed that the cities of New York, Baltimore, Norfolk, Long Island and Virginia Beach are declining by 2 mm annually. It turns out that the speed of the sea's advance over land in some areas in Delaware, Maryland, and South Carolina is three times faster.
It is clear from this that about 867,000 sites are at risk of being submerged, including highways, airports, railway lines, water pipelines, dams and buildings. In mapping the terrain and sites at risk of drowning, the researchers used satellite data, and the area of these lands is more than 3.6 thousand square kilometers.
